SPECIFICATION forming part of Letters Patent No. 758,684, dated-May 3, 1904. I

Application-filed September 16, 1903. Serial No. 173,484. (No model.)

To (all whom/.if muy concern:

'Be it known that we, Jolis S. Pneu, arcsident of Pittsburg, and ALBIN L. ZWARNIK, a `resident of Braddock, in the county of Allethe United States. have invented a new and useful improvement in Moistin'c-l-roof Cases or Receptacles, of which the following is a specification.

Our invention relates to casings or receptacles; and it has for its object to provide means forunaking such casings moisture-proof.

In the construction of transformer casings or receptacleshaving top and bottoni castings I and fiuted sheet-metal sides it has heretofore been unnecessary to make a water-tight joint between the top extension and the sides, because the level of the oil in which the transformer isimmersedhas been kept below the 2O joint. It is becominga usual practice to place in manholes or other suitable subterranean chambers the transformers employed in connelction with urban systems of electrical distribution, the distributing and supply mains .25 of which are placed in underground conduits.

In order to, fully protect such transformers,

it is necessaryfthat all joints be strictly moisture-proo'and to accomplish this resultwe provide a terne-plate 01 other suitable sheetmetal lining for the top extension.

Our invention is illustrated in the accompanying drawing, the single figure of which is a view in 'elevation of a partial section'of a casing constructed in accordance therewith.

The crushed ends 1 of the flutcd sheet-metal sides 2 are placed inA suitable grooves 3 in the lower edge of the top extension 4;, which is generally formed of cast metal. The top extension 4: is lined with terne-plate 5 or other 4o suitable sheet metal, the lower edge of which v is ,bent into the groove 3 and seated in solder 6, substantial-ly as shown, said solder being poured into the groove while in a molten state and the groove being of dovetail form in' cross- 515 section or being otherwise undercut to insure a iirm joint. The solder when cold securely anchorsthe sides 2 of the receptacle to the top l extension 4 and forms a'good'moistnre-proof jointbetween the tinned parts 2, 1, and ln order t'o facilltate the flowing of the hot solder, a piece. of tinned metal '7 may be placed g in thebottoin of the groove 3, as shown. The 5 gheny and btatc of Pennsylvania., citizens of upper edge of the sheet-metal lining 5 is bent over the upper flange 8 of the casting 4, and thereby forms afacc between which andthe corresponding face 9 of the cover 10 is placed a gasket 11, of rubber, soft metal, or other suitable material. The .cover 10 is clamped z tightly to the casting -Pby means of a plurali ity of bolts 12 and is providedwith an eyebolt 13 to facilitate the handling of the transformer. Vhon the transformer is in its proper position, the cyebolt 13 maybe removed and, one end of a vent-pipe substituted therefor, the other end being open to the air at any desired and proper place. The cover 10 is provided with lugs 14, which bear upon the transformer-supporting brackets 15, and thus serve to hold the transformer in position.v Oil may be introduced into the receptacle through an aperture 16, which is normally closed by a plug 17. The transformer-terminals maybe brought through apertures in the casing in` any suitable manner, the means lvhere shown for obtaining a moistureproof`7$ connection to the cables being no part of our present invention.-

The uted sides 2 may have their ends crushed or compressed, as indicated, or not, as desired, the joints betweensaid sides and the lining 5 being made substantially the same in'either case.v t t 4Vlfhile we have described ourlinvention as applied to receptacles employed for holding transformers,we desire it to be understood'tha't` 8 5vv vsuch receptacles may be otherwise utilized and that our invention is not to be construed as limited to any specific serviceto the exclusion of others to whichit may be applicable. Y,

lt isevident from the description and illus4` 9c, tration that we have provided a moisture-proof," casing or receptacle for transformers by profviding a soldered joint 1between tinned parts, one olf-Which forms a lining-for an upper-'extensio, and also a 'seat'or .face towhich acove; 19,5 is` securely clamped.

We claim es our inventiona 1. A cese or receptacle comprising fluted sheet-metal sides, a top extension, e cover for said extension, e gasket ande sheet-metal lining for Said extension "one edge of iwhich is soldered to seid.` lutedsides-and the other edge of which andthe gasket are'clzunped between between the cover and the top edge of the eX-" tension. i

A moisture-proof case or receptacle comprising sheet-metal sides, e cast-metal top extension, a sheet-metel lining for seid extension t having its lower edge soldered to the upper' edges of the sides, a cast-metal cover and nieans'for clamping the upper edgeof the lining between the cover and the upper edge o't the extension.

L A moisture-proof casing or receptacle i comprising sheetfnietel sides, a cast-metal top extension having an undercut groove in its lower edge, e sheet-inetl lining forsuid extension the lower edge of which is soldered to the top edges of the sides in said groove, u cast-metal cover end means foljclmnping the upper edge of" the lining between the `cover and the top edge of the extension.

1 f u5. A'cuse' `or receptacle comprising sheetmetal sides, e cest-metal top extension having a. groove in its lower edge in which the upper edges of the sides are seated, e sheet-metal lining for the extension the lower edge of whichvis also seated in seid groove, e body of solderlilling said groove eroundthe edges of the sides and lining, e cast-metal cover for the extension and means for clamping the upper edge of the lining between the coverand the u'pper edge of the extension.

1n testimony whereof we have hereunto subscribed our names this 1st day of September,
